Anthropic Claude API — Claude Mythos 5.1 — Event History

Anthropic opened Life Sciences Verification Program applications to the broader life-science community. Approved organizations can access Mythos through Anthropic's first-party API console under Standard Use grants; access remains vetted/approval-based. Native API pricing is unchanged at US$10/1M input and US$50/1M output tokens.

Initial canonical baseline for Anthropic Claude Mythos 5.1 on the native Claude API. Official pricing is $10/M input, $50/M output, $0.25/M cache reads, with 50% Batch API discounts; 1M-token context and 128K max output. Availability is Active but invite-only through Project Glasswing/trusted-access programs. This is a NEW event, not a price-change event.
